Investigating intra-individual variability of face scanning in autistic children.

Wang et al. (2022) watched how autistic children move their eyes while looking at faces. They measured how much each child’s own gaze path changed from moment to moment.

The team compared these within-child changes to those of non-autistic kids. No teaching or treatment was given; it was pure eye-tracking assessment.

Autistic children’s eyes jumped around faces in less predictable ways. One second they stared at the mouth, the next at the ear, then back to the mouth.

This higher moment-to-moment ‘jitter’ was tied to stronger social and repetitive-behavior symptoms.

Moya et al. (2022) saw the same kind of neural ‘jitter’ in brain signals during speech. Together the studies show variability is a cross-brain, cross-task marker in autism.

Kleinert et al. (2007) first showed autistic kids look less at eyes in moving social scenes. Qiandong extends that work by proving the pattern itself is unstable within the same child.

Deruelle et al. (2004) found autistic kids favor tiny face details. The new data say they also hop among those details more randomly, linking local bias to unstable scanning.

If a client’s gaze is highly variable, social drills that rely on steady eye contact may fail at first. Start with brief, highly structured face games and slowly lengthen the time the child must hold eye, nose, mouth gaze. Tracking gaze variability could also give you a quick, objective probe of session-to-session progress without extra paperwork.
